EFFECT OF POSTURAL VARIATION ON LUNG FUNCTION IN PATIENTS WITH MULTIPLE SCLEROSIS

Resumen

Introduction: Multiple Sclerosis (MS) is an autoimmune disease that causes demyelination and inflammation, affecting young adults, and its progression leads to reduction in respiratory muscle strength. Objective: To evaluate respiratory muscle strength (RMS) in the sitting and supine 90 ° to 0 ° in patients with MS and compare the values obtained with those of healthy individuals of the same gender and age. Methods: This is a cross-sectional study, quantitative, type Case Study, which evaluated the FMR by manometer in two different positions, sitting and supine 90 ° to 0 °. We evaluated 02 individuals with MS aged 22 (Case 1) and 57 (Case 2) years, females were also evaluated 02 healthy subjects. Data were analyzed and expressed as a percentage change. Results: It was observed that the FMR in MS patients is reduced by 50.44% compared to healthy individuals, in the sitting to 90 ° as in the supine position at 0 °. The effect of postural variation was noted that Case 1 showed better results for MIP and MEP in the sitting position and the second case, improvement was found in that same position, only the MEP. Conclusion: FMR in MS patients was lower compared with healthy individuals of the same gender and age, regardless of body position. The values of maximal respiratory pressures were higher when measured in a sitting position, but without great percentage difference compared with the supine position at 0 °.
